Definitions
- the present invention is directed generally to surgical devices for repair and reconstruction of soft tissue injuries and, more particularly, to a suture backstop system for loading an all-suture backstop on a suspension system in a bone tunnel.
- a replacement graft ligament is secured at the site of the original, now damaged, ligament.
- the repair and reconstruction of tom or damaged soft tissues is a common surgical procedure.
- replacement graft ligaments may be secured at the site of the original ligament.
- the procedure generally involves drilling bone tunnels into adjacent bones at the site of the original ligament and securing a graft ligament within these bone tunnels.
- the graft ligament may be an autograft, an allograft, a xenograft, or it may be totally artificial and synthetic.
- ACL anterior cruciate ligament
- grafts include ones which may be autologous or allograft bone-patellar tendon-bone or soft tissue (such as semitendinosus and gracilis tendons), both types harvested by techniques well known to those skilled in the art.
- the graft ligaments may be secured within the bone tunnels in a variety of ways. Of prime importance is the degree to which they can withstand pullout forces prior to complete healing. For example, it is known to use interference screws inserted parallel to the tunnel axis to compress the ends of the graft ligament against the wall of the bone tunnel to secure the graft ligament and promote tissue in-growth.
- Suspensory graft fixation devices have been developed to secure a graft ligament in a bone tunnel.
- One such device is described in U.S. Pat. No. 8,852,250 (Lombardo et al), entitled Graft Fixation Implant, assigned to the assignee hereof and incorporated by reference in its entirety herein.
- Suspensory graft fixation devices work by lying transversely across the opening of a bone tunnel and generally take the form of an elongated anchor member which suspends a graft retaining loop from a fixation point on the surface of a bone to which the graft is to be attached (in this case, a femur).
- the elongated member has an axis and a pair of suture receiving apertures symmetrically situated on the axis on opposite sides of the center of the elongated member.
- the elongated member often called a button, is adapted to be situated transversely across the exit opening of the bone tunnel on the lateral femoral cortex so that a supporting loop, generally made of suture material, can be suspended from the button and can extend into the bone tunnel from the suture receiving apertures of the button.
- the suture loop supports one end of a graft ligament passed through the loop.
- the term“suture” as used herein may be any type of filamentous material such as a biocompatible or bioabsorbable filament, ribbon, tape, woven or non-woven material capable of providing the loop support and the frictional resistance required by the device described herein.
- the elongated anchor member is initially aligned with the axis of the bone tunnel, and pulled through the tunnel to the exit at the distal end on the lateral femur.
- the suture loop and the bone tunnel must both be long enough to enable the elongated member to“flip” from an axially aligned orientation to a transverse orientation when it exits the bone tunnel.
- graft fixation requires preparation of a graft ligament of predetermined length.
- conventional art suspensory graft fixation devices have fixed loop lengths, they are produced in multiple sizes (ranging, for example, from loop lengths of 15 mm to 60 mm in 5 mm increments in the case of XO Button® implants made by ConMed Corporation, Largo, Fla.) in order to accommodate various graft and tunnel lengths that may be encountered during a surgical procedure.
- the fixed graft length and variations in tunnel and loop lengths can make conventional suspensory ligament fixation challenging.
- buttons or other backstops
- the surgeon loads the suture tails through the button and then ties down the construct.
- an all-suture construct such as a suture braid
- the user must pierce or weave the all-suture construct with the suture tails to create a button. This is a complicated process that can take numerous, time- consuming steps.
- Embodiments of the present invention are directed to a suture backstop system for loading an all-suture backstop on a suspension system in a bone tunnel.
- the suture backstop system has a backstop with a first end and a second end both extending in a distal direction.
- the system includes a first passing longitudinal element (such as a wire (e.g. may nitinol) or other element stiffer than suture, but could also be suture) woven through the backstop such that a first loop is created in the first passing longitudinal element and extends from the first end of the backstop.
- the system can also include a second passing longitudinal element (similar to the first passing longitudinal element) woven through the backstop such that a second loop is created in the second passing longitudinal element and extends from the second end of the backstop.
- the first and second passing longitudinal elements can be attached to a distal end of a handle.
- the suture backstop system has a backstop having a first end and a second end.
- the first and second ends are positioned and extend in a first direction in an undeployed configuration and are positioned and extend in a second direction, different from the first direction, in a deployed configuration.
- the system includes a first passing longitudinal element woven through the backstop such that a first loop is created in the first passing longitudinal element and extends from the first end of the backstop.
- the system also includes a second passing longitudinal element woven through the backstop such that a second loop is created in the second passing longitudinal element and extends from the second end of the backstop.
- the present invention is a method for suspending a first body in relative position to a second body.
- the method includes the steps of: (i) providing a suspension system comprising a length of suture with a pair of free limbs positioned through an anchoring body; (ii) passing the free limbs through a proximal first body and an adjacent distal second body such that the free limbs extend from a proximal surface of the first body and a portion of the anchoring body is positioned on a distal surface of the second body; (iii) providing a suture backstop system comprising a backstop having a first end and a second end both extending in a distal direction, a first passing longitudinal element woven through the backstop such that a first loop is created in the first passing longitudinal element and extends from the first end of the backstop, a second passing longitudinal element woven through the backstop such that a second loop is created in the second passing longitudinal element and extends from the second end of the backstop

- the suture backstop system 10 comprises a backstop 12 with a pair of passing longitudinal elements (as shown in this example, a first passing wire 14 and a second passing wire 16) woven therethrough.
- the backstop 12 may be a button, suspensory fixation device, or other anchor composed of any soft, flexible suture anchor material (similarly as discussed with respect to anchoring body 112 - including described functionality - with respect to FIGS. 6-7 below).
- a purpose of using an all-suture anchor backstop 12 and an all-suture button 112 is to minimize irritation and discomfort to the patient at the surgical site.
- the backstop 12 can be composed of suture braid.
- the backstop 12 can be composed of radiopaque fiber such that the backstop 12 can be seen in x-ray photographs.
- An all-suture backstop 12 minimizes irritation and discomfort to the patient at the surgical site.
- the passing wires 14, 16 can be composed of any suitable wire material, including but not limited to nitinol (which should be understood and appreciated by a person of ordinary skill in the art in conjunction with a review of this disclosure), as should be understood by a person of ordinary skill in the art in conjunction with a review of this disclosure, such as nitinol.
- the passing wires 14, 16 are woven through the backstop 12 such that a first loop 18 is created in the first passing wire 14 and extends distally from a first end 20 of the backstop 12, and a second loop 22 is created in the second passing wire 16 and extends distally from a second end 24 of the backstop 12.
- the first passing wire 14 is folded in half to create the first loop 18 and the limbs of the first passing wire 14 are woven through the backstop 12 in the proximal direction.
- the second passing wire 16 is folded in half to create the second loop 22 and the limbs of the second passing wire 16 are woven through the backstop 12 in the proximal direction.
- the passing wires 14, 16 pass through the backstop 12 a total of six (6) times (although, the number of pass throughs can vary, and can be an even number on one side and an odd number on another side of the backstop 12 (or both even or both odd)).
- the first loop 18 extends distally from the first end 20 of the backstop 12 and the first passing wire 14 is woven proximally through the backstop 12 at three passing locations 26, 28.
- the first passing wire 14 is woven such that it extends from the backstop 12 at a first central passing location 28 (as used herein,“central” describes a location on the backstop 12 closer to a midpoint or center of the backstop 12 as compared to the first or second end 20, 24 of the backstop 12).
- the second loop 22 extends distally from the second end 24 of the backstop 12 and the second passing wire 16 is woven proximally through the backstop 12 at three passing locations 30, 32.
- the second passing wire 16 is woven such that it extends from the backstop 12 at a second central passing location 32, which is adjacent to the first central passing location 28, as shown in FIG. 1.
- the backstop 12 is folded such that the first end 20 and the second end 24 are adjacent with the first loop 18 and the second loop 22 both extending in the distal direction, while the first and second passing wires 14, 16 extend in the proximal direction.
- the suture backstop system 10 of FIG. 1 also includes a handle 34.
- the handle 34 is rectangular; however any other suitable geometry can be used.
- the handle 34 may be molded such that it comprises one or more ridges 36 (or other projections) for increased gripping control for the user.
- the first passing wire 14 extending from the first loop 18 and the second passing wire 16 extending from the second loop 22 are attached to a distal end 38 of the handle 34, as shown.
- the suture backstop system 10 With the suture backstop system 10 in the pre-deployment configuration, as shown in FIG. 1, the suture backstop system 10 can be used to load the backstop 12 onto a suspension system for suspending or tensioning a first body in a desired position relative to a second body.
- FIGs. 6-7 there are shown side views schematic representations of a suspension system 100 in a partially deployed configuration, according to an embodiment.
- the suture suspension system 100 includes a length of suture 114 woven through an anchoring body 112, as described in U.S. Patent Application No. 15/711,192, assigned to the assignee hereof and incorporated by reference herein in its entirety.
- the anchoring body 112 is an all-suture button in an expanded position (FIG. 6) and in a compressed position (FIG. 5).
- the anchoring body 112 can be a suspensory fixation device as described in U.S. Patent No.
- an embodiment of the suspensory fixation device can include an elongated anchor member (which may or may not have preformed suture receiving apertures, where at least one of which can, but doesn’t have to be, recessed within a surface of the elongated anchor member), and a suture threaded through at least one of the apertures.
- the anchoring body 112 can be any soft suture anchor material (as should be understood by a person of ordinary skill in the art in conjunction with a review of this disclosure).
- soft anchors are commonly made entirely of suture materials, they are sometimes called“all-suture” anchors, and generally include a fibrous construct anchor body portion (or fibrous, braided or woven fabric-type structure such as a flexible web, as described in U.S. Pat. No. 9173652) along with a suture or filament portion.
- the fibrous construct can be flat, non-flat, and/or tubular or non-tubular.
- Another example of a“soft” all-suture anchor is the Y-Knot® device. See, e.g., U.S. 9826971.
- Such all-suture anchors can take advantage of Poisson’s ratio, which captures the following cause/effect relationship: compressing a material in a first direction causes the material to expand in direction perpendicular to the first direction (i.e., if compressed in the x-direction, the material will expand in the y-direction and/or z-direction), and stretching/lengthening a material in a first direction causes the material to contract in directions perpendicular to the first direction.
- the suture 114 is woven through the anchoring body 112 such that two free limbs 116 of suture 114 extend from the anchoring body 112.
- the anchoring body 112 can be a suspensory fixation device as described in U.S. Patent Nos. 9,700,403 and 9,931,197, assigned to the assignee hereof and incorporated by reference herein in its entirety.
- the anchoring body 112 can be any soft suture anchor material. The suture 114 is woven through the anchoring body 112 such that two free limbs 116 of suture 114 extend from the anchoring body 112
- a single hole 118-1 is formed through a first body 118, and a single hole 120-1 is formed through an adjacent second body 120.
- the first and second bodies 118, 120 may be soft tissue, bone, or a graft.
- each of the first body 118 and the second body 120 is bone.
- a length of suture 114 is positioned through the bone hole 118-1, through the bone hole 120-1, through an all-suture button 112, and advanced back through bone holes 120-1 and 118-1 to form the partially deployed configuration shown in FIGs.
- the free limbs 116 of the suture 114 are pulled proximally from the first bone 118 to set the all-suture button 112 against the distal surface 122 of the second bone 120.
- the all-suture button 112 moves from the expanded position (in FIG. 6) to a compressed position (in FIG. 7).
- the all-suture button 112 covers a surface area on the distal side 122 of the second bone 120 larger than the diameter of the bone hole 120-1 in the second bone 120.
- FIG. 2 there is a side view schematic representation of the suture backstop system 10 in a partially deployed configuration, according to an embodiment.
- the backstop 12 of the suture backstop system 10 can be used to create suspension between the first bone 118 and the second bone 120 (FIGs. 6-7).
- the free limbs 116 of suture 114 are pulled through the bone hole 118-1 such that they extend proximally from the proximal surface 128 of the first body 118.
- the free limbs 116 of suture 114 are then passed through the first and second loops 18, 22 in the suture backstop system 10, as shown in FIG. 2.
- FIG. 3 there is shown another side view schematic representation of the suture backstop system 10 in a partially deployed configuration, according to an embodiment.
- the free limbs 116 of suture 114 are passed through the first and second loops 18, 22, the free limbs 116 of suture 114 are tensioned distally and the handle 34 is simultaneously pulled proximally.
- the handle 34 is simultaneously pulled proximally.
- the first and second loops 18, 22 are pulled through the passing locations 26, 28, 30, 32 on the backstop 12.
- the free limbs 116 of suture 114 have been passed through the first and second loops 18, 22, the free limbs 116 are also pulled through the passing locations 26, 28, 30, 32 in the backstop 12 when the first and second loops 18, 22 are pulled through the backstop 12, leading to the partially deployed configuration shown in FIG. 3.
- the backstop 12 is now loaded on the suture 114 of the suspension system 100 (FIGs. 6-7). Further, the free limbs 116 of suture 114 extend distally toward the proximal surface 128 of the first bone 118 (FIGs. 6-7).
- FIG. 4 there is shown an additional side view schematic representation of the suture backstop system 10 in a partially deployed configuration, according to an embodiment.
- the handle 34 is again pulled in the proximal direction to slide the free limbs 116 of suture 114 all the way through the backstop 12 to create the partially deployed configuration shown in FIG. 4. Thereafter, the handle 34 be discarded or otherwise removed from the suture backstop system 10.
- the backstop 12 has been transferred to the free limbs 116 of suture 114 and is shown being moved distally along the suture 114 until it is against the proximal surface 128 of the first bone 118.
- additional tension in the free limbs 116 in the proximal direction causes the backstop 12 to move from an expanded position to a compressed position.
- the ends 20, 24 of the backstop 12 are in a first direction along a longitudinal axis.
- the ends 20, 24 of the backstop 12 can rotate to a second direction different than the first direction, as shown in FIG.
- the backstop 12 is in the deployed configuration, according to an embodiment.
- the free limbs 116 of suture 114 are tied over the backstop 12 in the compressed position, forming a knot 130.
- the knot 130 forces the backstop 12 to lay tight over the proximal surface 128 of the first bone 118 and particularly, the bone hole 118-1 (FIG. 8), to form the button and complete the repair.
- FIG. 9 shows a side schematic view of the knot 130 formed in the free limbs 116 of suture 114 proxima!ly over the backstop 12, i.e., the deployed configuration of the suspension system 100. Tying the knot 130 in the free limbs 116 secures the backstop 12 in the compressed and deployed position. Excess portions of the free limbs 116 of suture 114 that extend from the knot 130 can be trimmed and removed to decrease the potential for irritation and discomfort.
- a step of method or an element of a device that“comprises”,“has”,“includes” or“contains” one or more features possesses those one or more features, but is not limited to possessing only those one or more features.
- a device or structure that is configured in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
